URL: https://eid-privacy.github.io/wp1/2025/10/21/comparing-implemented-zk-systems.html

Summary

Comparative analysis of implemented ZKP systems for digital identity infrastructure. Categorises systems by family (hPKC, DLP, IP, MPC, ZK-STARK, IVC+hPKC) and evaluates prover resource efficiency, transparency, and post-quantum safety. Highlights Crescent and Longfellow as the two most promising approaches for ECDSA-signed credential use cases.
